petstairs! that's all I have to say...
althought they will STILL try to jump.. they'd much rather use the stairs..
Kayah jumps off of our bed

now she's a little fatty so I worry about her spraining her ankles or damaging her knees... And although Evie does jump off the couch once in a while... she's much lighter and the couch is much lower then our bed... but there's only so much you can do... they will do whatever they please... just in case she jumps again.. watch her.. if anything at all concerns you.. call your vet.. other than that... relax
